ZF 4616.337.005 GEAR for WG65 | OEM Genuine Part

Overview

The ZF 4616.337.005 GEAR is a precision-machined helical gear engineered specifically for the WG 65 series transmission. This OEM genuine component resides within the intermediate shaft assembly, where it facilitates torque transfer and speed reduction between the input and output stages. The SKU 4616.337.005 is manufactured to ZF’s exacting tolerances, ensuring minimal backlash and quiet operation under heavy load. When paired with a robust 4616105413: OUTPUT shaft, this gear maintains driveline integrity in demanding industrial applications.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth produce a distinct high-pitched sound, often mistaken for bearing failure. This indicates surface pitting or tooth profile wear on the 4616.337.005.
• Intermittent gear slipping under load: When the gear’s helix angle degrades, the transmission may momentarily lose torque transfer, especially during hill climbs or heavy hauling.
• Metallic debris in transmission fluid: Flakes or silver particles in the oil pan signal advanced gear wear. This symptom often accompanies damage to the 4616203017: OUTPUT FLANGE.
• Vibration through the shift lever: Excessive gear play transmits harmonic vibrations into the cab, worsening as the 4616101117: TRANSMISSION HOUSING alignment shifts.

Technical Specifications

Compatibility

This gear is a direct fit for the ZF WG65 series transmission family. It is also compatible with WG180, WG200, and WG250 models that share the same intermediate shaft architecture. Always verify the tooth count and spline interface before installation. The 4616.337.005 works in conjunction with the 0636011038: HEXAGON SCREW to secure the gear to its shaft. For complete rebuilds, consider replacing the 0636016015: HEXAGON SCREW and 0631306085: CYLINDRICAL PIN to ensure proper torque retention.
